Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating equipment, in particular to a heat exchange hydraulic module applied to a heating system.
Background Art
[0002] At present, there are two commonly used hot water heating systems on the market. One is a solar pressurized hot water system, which uses a solar collector to collect solar heat, and under the irradiation of sunlight, the solar light energy is fully converted into heat energy. Through a control system, functional components such as a circulation pump or a solenoid valve are automatically controlled to transfer the heat collected by the system to a large water storage and insulation tank, and with equivalent energy such as electricity, gas, and fuel, the water in the water storage and insulation tank is heated to become a relatively stable quantitative energy device. The other is a pressurized hot water HVAC heating system, which obtains an appropriate temperature inside a building through the design of the building and the cold-proof heating device. Since the internal liquid needs to absorb and release heat repeatedly, the pressure in the energy storage water tank is sometimes large and sometimes small. When the equipment ages, it is easy to rupture due to excessive internal pressure, posing a great potential safety hazard.
Content of the Utility Model
[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a heat exchange hydraulic module applied to a heating system.
[0004] The present application is achieved through the following technical solutions: A heat exchange hydraulic module applied to a heating system includes a housing, and a water tank, an internal pressure regulating device, and a water replenishing device provided inside the housing. The internal pressure regulating device and the water replenishing device are respectively communicated with the water tank, and the internal pressure regulating device includes an expansion tank and a safety valve respectively communicated with the water tank. The water tank has a first circulation port and a second circulation port communicated with a floor heating module, and an exhaust port communicated with the outside.
[0005] For the heat exchange hydraulic module applied to a heating system as described above, the water tank includes a first water tank and a second water tank which are respectively communicated and arranged. The expansion tank is communicated with the second water tank, the safety valve is communicated with the first water tank, and the first circulation port, the second circulation port, and the exhaust port are respectively communicated and arranged on the first water tank.
[0006] For the heat exchange hydraulic module applied to a heating system as described above, the internal pressure regulating device further includes a water pipe, a differential pressure bypass valve connecting the water pipe and the first water tank, and a water pump installed at one end of the water pipe. A third circulation port communicated with the floor heating module is provided at the other end of the water pipe, and a fourth circulation port communicated with the floor heating module is provided at the other end of the water pump.
[0007] The heat exchange hydraulic module applied to the heating system as described above, wherein the water replenishing device comprises a water inlet pipe communicated with the first water tank and a water replenishing valve installed on the water inlet pipe.
[0008] The heat exchange hydraulic module applied to the heating system as described above, wherein the volume of the second water tank is smaller than that of the first water tank.
[0009] Compared with the prior art, the present application has the following advantages:
[0010] The heat exchange hydraulic module of the present utility model applied to the heating system comprises a water tank, an internal pressure regulating device and a water replenishing device fixedly installed on the outer shell. The water tank is communicated with the floor heating module through the first circulation port and the second circulation port to supply heat externally. The water replenishing device replenishes water to the overall heating system. The expansion tank and the safety valve cooperate to absorb the expansion amount when the temperature of the working medium rises and the volume expands, preventing the system pressure from rising too fast. When the temperature of the working medium drops and the volume shrinks, the liquid in the airbag is released and supplemented to the system to prevent the system pressure from dropping too fast. The number of pressure reliefs of the safety valve and the number of water replenishments of the water replenishing device are reduced, which ensures the constant water pressure of the heating system, saves energy and prolongs the service life of the heating system.

Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

Detailed Embodiments
[0013] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0014] As Figure 1As shown in the figure, the embodiment of the present application proposes a heat exchange hydraulic module applied to a heating system, which includes a housing 1, and a water tank 2, an internal pressure regulating device 3, and a water replenishing device 4 disposed in the housing 1. The internal pressure regulating device 3 and the water replenishing device 4 are respectively communicated with the water tank 2. The internal pressure regulating device 3 includes an expansion tank 31 and a safety valve 32 that are respectively communicated with the water tank 2. The water tank 2 has a first circulation port 21 and a second circulation port 22 communicated with a floor heating module, and an exhaust port 23 communicated with the outside. Since the internal liquid needs to absorb and release heat repeatedly, the pressure borne in the energy storage water tank is sometimes large and sometimes small. When the equipment ages, it is easy to rupture due to excessive internal pressure, posing a great safety hazard. The present application includes that the housing 1 fixedly installs the water tank 2, the internal pressure regulating device 3, and the water replenishing device 4. The water tank 2 is communicated with the floor heating module through the first circulation port 21 and the second circulation port 22 to supply heat externally. The water replenishing device 4 replenishes water to the overall heating system. The expansion tank 31 and the safety valve 32 cooperate to absorb the expansion amount when the temperature of the working medium rises and the volume expands, preventing the system pressure from rising too fast. When the temperature of the working medium drops and the volume shrinks, the liquid in the airbag is released and replenished into the system to prevent the system pressure from dropping too fast. Reduce the pressure relief times of the safety valve 32 and the water replenishing times of the water replenishing device 4, which ensures the constant water pressure of the heating system, saves energy, and extends the service life of the heating system.
[0015] The water tank 2 includes a first water tank 24 and a second water tank 25 that are respectively communicated and arranged. The expansion tank 31 is communicated with the second water tank 25, and the safety valve 32 is communicated with the first water tank 24. The first circulation port 21, the second circulation port 22, and the exhaust port 23 are respectively communicated and arranged on the first water tank 24. The volume of the second water tank 25 is smaller than the volume of the first water tank 24. While increasing the water storage space, the first water tank 24 and the second water tank 25 respectively perform pressure balance, and the small volume of the second water tank 25 avoids placing the expansion tank 31, reducing the volume of the heat exchange hydraulic module.
[0016] The internal pressure regulating device 3 further includes a water pipe 33, a differential pressure bypass valve 34 that communicates the water pipe 33 and the first water tank 24, and a water pump 35 installed at one end of the water pipe 33. The other end of the water pipe 33 is provided with a third circulation port 36 communicated with the floor heating module, and the other end of the water pump 35 is provided with a fourth circulation port 37 communicated with the floor heating module. The differential pressure bypass valve 34 is used to control the differential pressure between the heat exchange hydraulic module and the floor heating module to avoid the water pipe from rupturing due to excessive pressure in the floor heating module.
[0017] The water replenishing device 4 includes a water inlet pipe 41 communicated with the first water tank 24, and a water replenishing valve 42 installed on the water inlet pipe 41. The water replenishing valve 42 controls the water replenishing amount to prevent the liquid pressure or temperature change in the first water tank 24 from being too large.
[0018] As described above, one or more embodiments are provided in combination with specific contents, and it is not determined that the specific implementation of this application is only limited to these descriptions. All those that are similar or identical to the method, structure, etc. of this application, or those that make several technical deductions or substitutions under the premise of the concept of this application should be regarded as the protection scope of this application.
